imshow supports interpolation and that's why rasterization comes in.
If you turn off interpolation (w/ interpolation="none"), the original
image will be embedded. Of course dpi has no meaning in this case.

However, I agree with you that dpi should be a property of the backend
only, not the figure. But I am not sure if this can be fixed soon. It
will be difficult and will take lots of effort I think.
